# Clean
#

# The default clean target is very heavy for an already clean tree because it
# regenerates all the Makefiles from Makefile.fpc files to be able to call all
# the upstream distclean targets. Therefor the clean target is split into
# multiple components and you can fool the makefiles target when ZERO generated
# Makefiles are found by setting the variable MAY_FOOL_CLEAN to anything but
# the empty string. This is propably a reasonable trade-off under all
# circumstances, but to prevent anything bad from happening during official
# builds, it is not the default.
